Abstract (en)
[origin: WO2019155014A1] A method of shaping an article from a zinc or zinc alloy coated steel blank, comprising the steps of: a) providing a blank of the zinc or zinc alloy coated steel; b) reheating of the blank obtained in step a) to a reheating temperature TRH in the range Ac3 – 200°C of the steel; c) soaking the blank for a time up to 3 minutes at the reheating temperature TRH; d) shaping the article in a press; and e) cooling the article. The steel consists of (in wt.%) C: 0.01-0.2; Mn: 3.1-9.0; Al: 0.5-3.0; and optionally further alloying elements selected from Si, Cr, V, Nb, Ti and Mo; inevitable impurities and the balance is Fe.
